Time Travel Impossible - Again?

A team of Chinese physicists have put the time travel debate to bed. Their research concludes that a photon can not travel faster than light.

From the article:

• By result, the possibilities of time traveling have been debunked in one fell swoop because it was previously believed that if a single photon could travel faster than the speed of light, it could "teleport" information to another time.

Professor Shengwang Du, Assistant Professor in Hong Kong University of Science & Technology's Department of Physics, study demonstrates that a single photon has to obey the same laws of the universe just as any other Electro-Magnetic wave.

Professor Du points out that by showing that single photons cannot travel faster than the speed of light, his research also demonstrates the true speed of information carried by a single photon,
thus giving scientists a better picture on the transmission of quantum information."
